The SS United States’ on-again, off-again departure is on again. And it starts Thursday morning, unless delayed by an overnight storm expected to deliver a wintry mix to the city.

The ship could leave Philly by Saturday, weather permitting. Things are allegedly looking up for the SS United States and the vessel could be on the road to its temporary home by Saturday, with a micro-move from one Philadelphia pier to another scheduled for early Thursday morning.

The ship is scheduled to begin its move to Okaloosa County, Florida, on Thursday and depart Philadelphia on Saturday morning.

Plans to move the SS United States from Philadelphia to Mobile have once again been delayed. The U.S. Coast Guard has requested the delay to ensure a proper tow from both piers. Due to the delay, the plans for the ship to depart on Saturday at 4 a.
